Subject [jira] [Commented] (LUCENE-4894) Facet User Guide for lucene 4.2 has deleted classes/methods and needs more explanations.
Date Tue, 02 Apr 2013 20:29:17 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4894?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13620245#comment-13620245

crocket commented on LUCENE-4894:
---------------------------------

However, without facet user guide, I wouldn't have known that it ever existed.
You may still need to advertise the facet module in http://lucene.apache.org/core/4_x_x/index.html

>             Project: Lucene - Core
>          Issue Type: Bug
>          Components: general/website, modules/facet
>    Affects Versions: 4.2
>            Reporter: crocket
>            Priority: Minor
>
> * Concurrent Indexing and Search
> There is no clear explanation regarding those points below.
> 1. TaxonomyReader should be reopened after IndexReader.
> 2. TaxonomyWriter should be committed before IndexWriter. TaxonomyWriter should be closed
before IndexWriter.
> The rationale is that it's ok to see categories to which no document belongs but not
ok the other way around.
> Beginners may not be able to see this until after they think through it for a long time,
which most of them including me wouldn't do.
> However, facet user guide doesn't explain the rationale clearly.
> * DocumentBuilder & FacetSearchParams.addFacetRequest
> They no longer exist in lucene 4.2, but they are used in code examples.
> * FacetResultNode.getLabel(TaxonomyReader)
> It doesn't eixst in 4.2, but it is mentioned in "Multiple Facet Requests"
> * ETC
> I don't know if there are other points to be made.
